It is really a question that requires a specific consultation with an immigration attorney and very soon. Generally, for adoption to work you will need to be adopted before you turn 16, so you have very little time (probably not enough).
There are a few options that may be available to you but information is needed and, because of the sensitive nature of your situation, you should consider sitting down and talking with an immigration attorney in person to learn about what options may be available to you.
Best of luck to you and great job on your grades!!

As my colleagues have noted, you should consult in private with an immigration attorney to discuss your case in detail and determine what options may be available. The adoption itself will not help you because there is not enough time for it to occur before your 16th birthday, and unfortunately your uncle cannot file a family-based petition for you. But other relief, including asylum, may be available depending on your situation. Good luck!
